A technique for fabrication of polydimethylsiloxane-acrylic resin obturators.

A flexible silicone obturator is an alternative to the acrylic resin obturator. It can be useful for patients with severe trismus who cannot insert a large prosthesis, as the flexibility of the hollow silicone section allows easy placement and removal (Fig. 9). Other patients cannot tolerate an unyielding substance against sensitive nasal tissues. Silicone can provide the necessary comfort without compromising retention. Silicone obturator sections can often be modified when further surgery is needed and result in a savings of time and expense (Fig. 10). For patients who can be reevaluated only twice a year, several silicone obturator sections can be made initially. One can be used while another is being cleaned or duplicated.
